Two devices sending data via Bluetooth to one device

Hi I want to do a project where two nano with each one of them connected to some sort of Bluetooth module (ideally BLE type) and send data to an arduino mega. But it seems like HC-05 and HC-06 can only do 1-1 sending and receiving. What module should I use to allow the mega to make multiple Bluetooth connections and receive data from two separate arduinos?

This is what Bluetooth does.

For shure if you implement a master/slave software protocol.
